--- Comment #22 from Kevin Meyer billy65bob@gmail.com 2010-05-21 22:48:19 --- After some time of playing, Arcanum freezes. wine's output tells me it's out of GDI handles, so this is still an issue.
There's also a very noticible change when running arcanum normally. the GDI backend renders without corruption, but does so very very slowly. The OpenGL one crashes at the mainmenu so I couldn't test that further.
For those playing with the OpenGL backend (in safe mode) to avoid the issue, note that the OpenGL backend is also incredibly slow unless you set HKEY_CURRENT_USER\Software\Wine\Direct3D\RenderTrgetLockMode to readdraw (default is readtex)
